Q
- What is an advantage in using a packet filtering firewall versus a high-end firewall appliance?
Packet filters perform almost all the tasks of a high-end firewall at a fraction of the cost.
Packet filters provide an initial degree of security at the data-link and network layer.
Packet filters represent a complete firewall solution.
Packet filters are not susceptible to IP spoofing.

Q
- A network administrator enters the single-connection command. What effect does this command have on AAA operation?
allows a new TCP session to be established for every authorization request
authorizes connections based on a list of IP addresses configured in an ACL on a Cisco ACS server
allows a Cisco ACS server to minimize delay by establishing persistent TCP connections
allows the device to establish only a single connection with the AAA-enabled server
A
allows a Cisco ACS server to minimize delay by establishing persistent TCP connections

Q
- Which two practices are associated with securing the features and performance of router operating systems? (Choose two.)
Install a UPS.
Keep a secure copy of router operating system images.
Configure the router with the maximum amount of memory possible.
Disable default router services that are not necessary.
Reduce the number of ports that can be used to access the router.
A
Keep a secure copy of router operating system images.
Configure the router with the maximum amount of memory possible.
5
Q
- Which statement describes a characteristic of the IKE protocol?
It uses UDP port 500 to exchange IKE information between the security gateways.
IKE Phase 1 can be implemented in three different modes: main, aggressive, or quick.
It allows for the transmission of keys directly across a network.
The purpose of IKE Phase 2 is to negotiate a security association between two IKE peers.
A
It uses UDP port 500 to exchange IKE information between the security gateways.
6
Q
- Refer to the exhibit. If a network administrator is using ASDM to configure a site-to-site VPN between the CCNAS-ASA and R3, which IP address would the administrator use for the peer IP address textbox on the ASA if data traffic is to be encrypted between the two remote LANs?
- 165.201.1
- 168.1.3
- 16.3.1
- 16.3.3
- 168.1.1
A
209.165.201.1

Q
- Refer to the exhibit. Based on the security levels of the interfaces on the ASA, what statement correctly describes the flow of traffic allowed on the interfaces?
Traffic that is sent from the LAN and the Internet to the DMZ is considered inbound.
Traffic that is sent from the DMZ and the Internet to the LAN is considered outbound.
Traffic that is sent from the LAN to the DMZ is considered is considered inbound.
Traffic that is sent from the DMZ and the LAN to the Internet is considered outbound.
A
Traffic that is sent from the DMZ and the LAN to the Internet is considered outbound.
8
Q
- What two assurances does digital signing provide about code that is downloaded from the Internet? (Choose two.)
The code contains no errors.
The code contains no viruses.
The code has not been modified since it left the software publisher.
The code is authentic and is actually sourced by the publisher.
The code was encrypted with both a private and public key.
A
The code has not been modified since it left the software publisher.
The code is authentic and is actually sourced by the publisher.

Q
29. Which interface option could be set through ASDM for a Cisco ASA? default route access list VLAN ID NAT/PAT
A
VLAN ID
10
Q
- What are two characteristics of a stateful firewall? (Choose two.)
uses connection information maintained in a state table
uses static packet filtering techniques
analyzes traffic at Layers 3, 4 and 5 of the OSI model
uses complex ACLs which can be difficult to configure
prevents Layer 7 attacks
A
uses connection information maintained in a state table
analyzes traffic at Layers 3, 4 and 5 of the OSI model
11
Q
- What are three characteristics of SIEM? (Choose three.)
can be implemented as software or as a service
Microsoft port scanning tool designed for Windows
examines logs and events from systems and applications to detect security threats
consolidates duplicate event data to minimize the volume of gathered data
uses penetration testing to determine most network vulnerabilities
provides real-time reporting for short-term security event analysis
A
can be implemented as software or as a service
examines logs and events from systems and applications to detect security threats
